Ditching the simple 16×4 LCD, version 2 sports a full color 320×240 touch panel LCD. A faster STM32 micro controller replaces the Atmega88 he used the first time around, allowing him to create a much more advanced user interface. The micro runs the ChibiOS/RT real time operating system, which enables multitasking, making the entire project a lot easier. Like the first version, an original Fonera performs all of the pen testing, though this time around he has ditched the vanilla DD-WRT distro for Jasager, which is purpose-built for running the Karma attack.

The project is coming along nicely, and [Emeryth] says he has a few simple apps running on the device already. He has found that running several applications on the device simultaneously is testing the practical limits of the Foneras capabilities, though he may add more memory to the router in order to squeeze a little more life out of it.

Inside this box you’ll find a La Fonera wireless access point. [Emeryth] and his band of miscreants built this portable device for WiFi security testing. The AP is running OpenWRT and has been set up to use the 16×4 character display as a terminal. An ATmega88 connects the LCD as well as six buttons to the UART of the La Fonera. From there, a set of Ruby scripts takes care of the communication protocol. As you can see after the break, this setup allows you to scan the area for WiFi, showing channel, SSID, and MAC information. Although not specifically outlined in the video we suspect there’s some more devious tricks up its sleeve too.

La Fonera’s are getting pretty popular lately. [Lefinnois] hacked his to get i2c working. He used a 75LS05 to adapt the io levels, and some bit banging in the software to pull it off. Now the Fonera can be used for inexpensive remote monitoring via inexpensive i2c devices. Not to mention that this could provide a cheap network interface for various micro-controller projects. (I’m thinking networked thermostat for my new house.)
